Levels of soybean pest attacks on study of soya plant technology package in acid dry land soils in South Lampung

Abstract

One obstacle in soybean cultivation is the presence of pests and diseases. The concept of IPM is a concept of pest control that arises and develops due to human awareness of the dangers of pesticide use that continues to increase both for the environment and public health. This study aimed to determine the intensity of attack by major plant diseases and the number of natural enemies in soybean plants on acid dry land and the population of natural enemies in Lampung This research was conducted in Margototo Village, Metro Kibang District, East Lampung Regency. This study used a randomized block design (RBD) and 10 replications, the treatment plot size was 500 m2 by 30 plots. in each treatment 10 random sample plants were determined with 3 technology packages, which are technology for farmers (A), specific location technology (B), recommendations technology (C). Data analysis used Minitab. The results showed that at plant age 35 Days After Planting (DAP) for armyworm attacks ranged between 17.6 - 18.4%, however there was no significant difference between treatments. The attack of leaf folding ranged between 0.8-7.6% and the highest in treatment A was significantly different from treatment B and C. In general, the highest intensity of pest and disease attacks (gray, leaf folding and leaf rust) was in treatment A and significantly different from treatment B and C. While the existence of the highest natural spider enemies in treatment B and C, compared to treatment A. However, the existence of natural enemies, Menochilus sp., was not significantly different between treatments.

Genome-Wide Association Analysis for Resistance to Coniothyrium glycines Causing Red Leaf Blotch Disease in Soybean

“…Identifying novel sources of resistance in soybean germplasm to key biotic and abiotic stress is an essential determinant for enhancing productivity [ 91 , 92 ]. Extensive work on the genetic improvement of soybean to resistance to selected diseases and pests [ 92 ] and other nutritional value [ 93 ] has been conducted across the world, but limited efforts have been made in the area of red leaf blotch disease in soybean [ 26 ].…”
